            AMENDED AND RESTATED STOCK PLEDGE AND SECURITY AGREEMENT

      THIS AMENDED AND RESTATED STOCK PLEDGE AND SECURITY AGREEMENT (the
"Agreement ") is made as of April 23, 2004, by BRIGHTSTAR CORP., a Delaware

                             Preliminary Statements

      (a) The Pledgor entered into a stock pledge and security agreement dated
May 24, 2002 (the "Original Pledge Agreement"), in favor of Motorola, Inc.

      (b) The Pledgor and the Secured Party desire to amend the Original Pledge
Agreement and to restate it in its entirety as so amended.

      NOW, THEREFORE, in consideration of the foregoing and other good and

Agreement in its entirety as follows:

Agreement amends, restates and replaces the Original Pledge Agreement in its
entirety. It is the intention and understanding of the parties that (a) this
Agreement shall continue the obligations under the Original Pledge Agreement

shall not act as a novation of the Original Pledge Agreement (or any Brightstar
Obligations represented, guarantied or secured thereby), (b) all guaranties and
all security interests, pledges and other liens guarantying or securing the
Original Pledge Agreement (or any Brightstar Obligations represented, guarantied
or secured thereby) shall remain in full force and effect and shall guarantee
and secure this Agreement (and all Brightstar Obligations represented,
guarantied or secured thereby), and (c) the priority of all guaranties and all
security interests, pledges and other liens guarantying or securing any
obligations under the Original

Pledge Agreement (or any Brightstar Obligations represented, guarantied or
secured thereby) shall not be impaired by the execution, delivery or performance
of this Agreement.

      3. Creation of Security Interest. To secure the prompt payment and
performance of the Brightstar Obligations, the Pledgor hereby grants, bargains,
hypothecates, assigns, transfers, sets over to the Secured Party, a first
priority security interest in and to the Collateral. Until termination of the
security interest as provided hereinafter, the pledge, assignment, transfer,
setting over, conveyance and delivery of, and security interest in, all the
Collateral hereby shall continue in full force and effect.

      4. Representations and Warranties. The Pledgor represents and warrants to
the Secured Party, as follows:

            (a) Collateral.

                  (i) The Pledgor has all right, title and interest in and to
      the Collateral, and that the Pledgor shall warrant and defend the Secured
      Party's security interest against the claims of all persons whomsoever.

                  (ii) Except as granted herein, the Collateral is not subject
      to any agreement, trust, pledge, charge, option, restriction, claim,
      demand, security interest, lien or encumbrance or any kind or nature and
      the Pledgor has not disposed of any interest in the Collateral.

                  (iii) The Pledgor has full right, power and lawful authority
      to transfer, convey, assign and pledge the Collateral to the Secured
      Party.

                  (iv) This Agreement creates and constitutes and will at all
      times constitute a valid, direct and paramount security interest in the
      Collateral.

                  (v) The Pledgor has complied with all foreign, federal and
      state laws and regulations applicable to the pledge of the Collateral, and
      no consents are required to make the pledge effective.

            (b) The Pledged Stock. The Pledgor owns all of the ownership, voting
and all other rights in 9,000 shares of the capital stock of Brightstar US,
Inc., a Florida corporation ("Brightstar US"). All of the foregoing right,
title and interest of the Pledgor, and all shares resulting from the exercise of
any options, warrants or other contractual rights to acquire additional shares
in Brightstar US and all distributions on all of the foregoing, whether in kind,
in the form of additional shares of stock of Brightstar US or in cash, is
subject to the pledge being granted herein, and all of the foregoing is referred
to as the "Pledged Stock". To the extent any of the foregoing may also be
considered Proceeds, the characterization shall be such as better protects the
security interest of the Secured Party, it being the intent of the parties
hereto that the characterization of the interests being granted herein should
not adversely effect the Secured Party.

            (c) Further Representations and Warranties. The execution, delivery
and performance of this Agreement will not (A) violate any provisions of (i)
law; (ii) any order of

   Amended and Restated Stock Pledge Agreement (Brightstar US Stock) - Page 2

<PAGE>

any court or other agency of government applicable to the Pledgor or its
property; or (iii) any agreement to which the Pledgor is a party or by which the
Pledgor or any of its properties is bound, or (B) be in conflict with, result in
a breach of or constitute (with due notice or lapse of time or both) a default
under, any such indenture, agreement or other instrument, or result in the
creation or imposition of any lien, charge or encumbrance of any nature
whatsoever upon the Collateral.

      5. Affirmative Covenants of the Pledgor. The Pledgor covenants and agrees
with the Secured Party that the Pledgor will:

            (a) Deliver Collateral. (i) Deliver to the Secured Party

may request, including but not limited to stock powers endorsed in blank, in
order to assign to the Secured Party and confirm unto the Secured Party the
pledge of all rights of the Pledgor arising from the ownership of the Pledged
Stock. At the time of execution hereof, there are 10,000 shares of Brightstar US
stock issued and outstanding and the record and beneficial ownership thereof is
as follows: the Pledgor, 9,000 shares; Denise Gibson, 1,000 shares. Delivery and
custody of the Pledged Stock will be in the manner selected by the Secured Party
and shall be held by such persons as the Secured Party, in its discretion, may
designate.

            (b) Transfer Legends. (i) Cause the issuer of the Pledged Stock (a)
to maintain appropriate stop transfer legends in its corporate stock record
books prohibiting any attempted transfer thereof by the Pledgor; and (ii) to
place on each of the stock certificates evidencing the Pledged Stock a legend in
form acceptable to the Secured Party to the general effect of serving to notify
any third party of the security interest of the Secured Party in the Pledged
Stock evidenced by the particular stock certificate.

            (c) Other Provisions. Comply with each and every other provision of
this Agreement and promptly do or refrain from doing such acts as the Secured
Party may reasonably request to effectuate the provisions and purposes of this
Agreement.

            (d) Representations and Warranties. Perform such other actions as
may be necessary to ensure that all representations and warranties made
hereunder shall be true and correct during the term hereof.

      6. Negative Covenant of the Pledgor. The Pledgor covenants and agrees with
the Secured Party that it will not contract, create, assume, incur or suffer to
be created, assumed or incurred or to exist any mortgage, lien, security
interest, charge or encumbrance of any kind, upon, or pledge of, any of the
Collateral other than that in favor of the Secured Party, or attempt to sell,
transfer or convey any interest in the Collateral, and will pay or cause to be
paid prior to delinquency all taxes, fees, assessments or other charges now or
hereafter imposed upon the Collateral.

      8. Rights and Remedies of the Secured Party. Upon the occurrence of any
Default or Event of Default, then and in addition to all other rights and
remedies set forth herein:

            (a) The Secured Party shall have the right from time to time, in any
commercially reasonable manner, to sell, resell, assign, transfer and deliver
all or any part of, or otherwise realize the value of any of the property in
which the Secured Party has a security interest hereunder, at any brokers' board
or exchange, or at public or private sale or otherwise, at the option of the
Secured Party, for cash or on credit for future delivery, in such parcel or
parcels and at such time or times and at such place or places, and upon such
terms and conditions as the Secured Party may deem proper, and in connection
therewith may grant options and may impose reasonable conditions, all without
(except as shall be required by any applicable statute which cannot be waived)
advertisement or demand upon or notice to the Pledgor or right of redemption of
the Pledgor, all of which are hereby expressly waived, except where any such
rights cannot be waived under any applicable law;

            (b) Upon any public sale, the Secured Party may, unless prohibited
by any applicable statute which cannot be waived, purchase all or any part of
any such property being sold, free from and discharged of all trust, claims,
rights of redemption and equities of the Pledgor, which are hereby waived and
released, unless preserved by any applicable statute which cannot be waived;

            (c) The Secured Party shall have the right to receive, endorse,
assign or deliver in its own name or the name of the Pledgor any and all checks,
drafts and other instruments for the payment of money relating to the Collateral
and the Pledgor hereby waives notice of presentment, protest and nonpayment of
any instruments so endorsed. In furtherance of the foregoing, the Pledgor hereby
irrevocably appoints the Secured Party, or any of its officers or designees, as
the Pledgor's true and lawful agent and attorney-in- fact, with power of
substitution, (i) to sign the name of the Pledgor to any Collateral pledged
hereunder, including, but not limited to, transferring such Collateral in the
name of the Secured Party or its assigns; (ii) to commence and prosecute any and
all suits, actions or proceedings at law or in equity in any court of competent
jurisdiction to collect or otherwise realize on all or any of the Collateral or
to enforce any rights in respect thereof; (iii) to settle, compromise, compound,
adjust or, defend any actions, suits or proceedings relating to or pertaining to
all or any of the Collateral; (iv) to execute such other and further grants,
mortgages, pledges and assignments of the Collateral as the Secured Party may
reasonably require for the purpose of protecting or maintaining the security
interest granted to the Secured Party; (v) to vote the Collateral, or any of it,
in such manner and for such purposes as the Secured Party may, in its sole and
absolute discretion, desire, including, but not limited to, voting to remove any
or all of the then existing directors, officers or partners of the issuer of the
Pledged Stock or any subsidiary thereof and selling the Collateral on such terms
as the Secured Party shall desire; provided, however, unless and until an Event
of Default has occurred and has continued beyond the expiration of any
applicable cure period, that the foregoing shall not prohibit the Pledgor from
voting or collecting dividends with respect to the Collateral if not prohibited
under any agreement with the Secured Party; and (vi) generally to

   Amended and Restated Stock Pledge Agreement (Brightstar US Stock) - Page 4

<PAGE>

perform all other acts the Secured Party in its sole discretion deems necessary
or proper to carry out the intention of this Agreement, as fully and completely
as though the Secured Party were the absolute owner of the Collateral for all
purposes, and the Pledgor hereby ratifies and confirms all that the Secured
Party, as such agent or attorney- in-fact, or its substitutes, shall do by
virtue of this appointment and grant of power. The Pledgor agrees that the
Secured Party may notify the issuer of the Pledged Stock that the Collateral has
been assigned to the Secured Party or of the Secured Party's security interest
therein, and that the Pledgor shall deal with the Secured Party directly. The
Secured Party shall not be responsible nor liable for any shortage, discrepancy,
damage, loss or destruction of any part of the Collateral wherever the same may
be located regardless of the cause thereof, including, in particular, the
negligence of the Secured Party, unless the same shall happen through gross
negligence or willful misconduct of the Secured Party. The Secured Party shall
not, under any circumstances or any event whatsoever, unless the same shall
happen through gross negligence or willful misconduct of the Secured Party, have
any liability for any error or omission or delivery of any kind made in the
settlement, collection or payment of any of the Collateral or of any instrument
received in payment therefor or for any damage resulting therefrom. The
foregoing limitation of liability shall apply regardless of whether such loss
shall be caused by the negligence of the Secured Party. The costs of collection,
notification and enforcement, including, but not limited to, counsel fees and
out-of-pocket expenses, shall be borne solely by the Pledgor, whether the same
are incurred by the Secured Party or the Pledgor;

            (d) The Pledgor will, upon the receipt by it of any payments,
revenue, income, profits or other sums in which, or resulting from any
Collateral in which a security interest is granted by this Agreement or of any
check, draft, note, trade acceptance or other instrument evidencing an
obligation to pay any such sum, hold the same in trust for the Secured Party in
precisely the form received, and will forthwith, without any notice or demand
whatsoever (all notices, demands or other actions on the part of the Secured
Party being hereby expressly waived), endorse, transfer and deliver any such
sums or instruments, or both, to the Secured Party for prompt application to the
payment of the Brightstar Obligations in a manner satisfactory to the Secured
Party; and

            (e) The Secured Party shall have the right to require the Pledgor to
notify the issuers of securities pledged hereunder or the paying agents therefor
to make payments owed thereunder directly to the Secured Party, and to collect
any or all accounts or proceeds, or to sell, transfer, compromise, discharge,
extend or sue for the whole or any part of such accounts.

            (f) The Secured Party will exercise its remedies under this Section
6 in accordance with the applicable provisions of Chapter 679 of the Florida
Statutes.

      9. Notification of Disposition. If any notification of intended
disposition of any property described herein or of any other intended action of
the Secured Party is required by any applicable law, such notification shall be
deemed reasonably and properly given if mailed to the Pledgor at the address set
forth herein at least ten (10) Business Days before such disposition or other
intended action.

      10. Remedies Cumulative. All options, powers and rights granted to the
Secured Party hereunder, or under any guarantee or other document or writings

options, powers or rights which the Secured Party may now or hereafter have as a
secured party under the Florida Uniform Commercial Code or under any other
applicable law or otherwise.

      11. Expenses, Etc. The Pledgor will reimburse the Secured Party for all
reasonable expenses (including reasonable expenses for legal services of every
kind) of, or incidental to the enforcement of any of the provisions of, this
Agreement or any actual or attempted sale, or any exchange, enforcement,
collection, compromise or settlement of any of the Collateral and for the care
of the Collateral and defending or asserting the rights and claims of the
Secured Party in respect of the Collateral, by litigation or otherwise,
including, but not limited to, reasonable fees and expenses of counsel for the
Secured Party. All such expenses shall be secured by this Agreement.

      12. Delay. No delay on the part of the Secured Party in exercising any of
its options, powers or rights, or partial or single exercise thereof, shall
constitute a waiver thereof.

      13. Application of Proceeds. All proceeds received from the sale or other
disposition of the Collateral shall be applied by the Secured Party as follows:

            (a) First: to the payment of all costs and expenses incurred by the
Secured Party in connection with any such sale or collection of the Collateral,
including, without limitation, all court costs and the reasonable fees and
expenses of counsel for the Secured Party in connection therewith, and the
payment of all costs and expenses paid or incurred by the Secured Party in
connection with this Agreement, or the exercise of any right or remedy hereunder

            (b) Second : to the payment of all other Brightstar Obligations;

            (c) Lastly: the balance, if any, of such proceeds remaining after

      15. Secured Party's Duty of Care. The Secured Party's duty with respect to
the Collateral shall be solely to use reasonable care in the physical custody
and physical preservation of such Collateral in its possession and the Secured
Party shall not be obligated to take any steps necessary to preserve any rights
in any of such property against third parties and the Pledgor agrees to take
such steps. The Secured Party shall have no responsibility for ascertaining, nor
for informing the Pledgor with respect to, nor be required to take any action
concerning, any maturities, calls, conversions, exchanges, offers, tenders or
similar matters relating to any of the property of the Pledgor (whether or not
the Secured Party has, or is deemed to have, knowledge of any of the aforesaid),
provided that the Secured Party shall endeavor to take such action as may be
requested or authorized by the Pledgor if the Secured Party determines, in its
sole discretion, that such action will not in any way adversely affect the value
of the Collateral or the

   Amended and Restated Stock Pledge Agreement (Brightstar US Stock) - Page 6

<PAGE>

ability of the Secured Party to realize upon the value of such Collateral. The
Secured Party shall not be bound to take any steps necessary to preserve any
rights in any of the property of the Pledgor against prior parties who may be
liable in connection therewith.

      16. Further Assurances. The Pledgor agrees to do or refrain from doing any
and all such further acts and things, and to execute and deliver such additional
conveyances, assignments, agreements and instruments, as the Secured Party may,
in its sole and absolute discretion, at any time request in connection with the
administration and enforcement of this Agreement, or with respect to the
Collateral or any part thereof or in order better to assure and confirm unto the
Secured Party its respective rights and remedies hereunder.

      17. Rights and Remedies of the Pledgor. Subject to the terms hereof, the
